Weber Ignition Timing

Since getting my Weber carb installed it sometimes takes a couple of goes to start the engine, otherwise all running great and if I give it a little bit of gas on ignition it starts fine.

I'm just wondering if the ignition timing might need to be adjusted? I've no idea what it's set to at the moment btw

Which Weber is it, the 32/36? For the basic setting it's two full turns out on the mixture screw, then alter with1/4 turns

Thanks.

I've noticed a weird 'whump' type noise a couple of seconds after I lift off the gas, could this be something to do with the mix being too rich or the timing being off?

I’d be inclined to get it set up properly on a rolling road - it’s not overly expensive and well worth doing.

Where about’s are you based and maybe someone can provide some info.
